Did the gdparent/ggrdparent pass the total cMs to mnay chromosomes or each generation left out chr. 6 [pick one]. And they the comparision of such to the next generation. Similarly to our family history research, the more exhaustive analysis we do helps to link our DNA to our ancestors, our matches and the scientific community. Thanks for a great review of DNA inheritance.Anonymoushttps://www.blogger.com/profile/11680740956718759137noreply@blogger.comtag:blogger.com,1999:blog-5415306683169000572.post-25831264869938148222017-10-06T11:59:10.042-07:002017-10-06T11:59:10.042-07:00Since you brought up terminology, as I prepared ma...Since you brought up terminology, as I prepared material for a class I was teaching I learned that some DNA researchers have used x-DNA to indicate a type of tagged DNA used for research and so I have begun to refer to DNA results from the X-chromosome as "X-chromosome-DNA" (just to be absolutely clear). Yes, it seemed clunky at first, but as I get used to it, it's become a habit. After all, clarity and consistency is key.Annahttps://www.blogger.com/profile/01989261931877747959noreply@blogger.comtag:blogger.com,1999:blog-5415306683169000572.post-69056670642762702632017-10-06T09:00:27.111-07:002017-10-06T09:00:27.111-07:00Alasdair, you raise a good point.

For most of us working primarily in the genealogical era, this has not yet emerged as a major issue. However, when we turn more anthropological and work with haplogroups going back into prehistory, this can become an issue. OK, I think you have persuaded me to standardize on "atDNA" in my writing from now on. Thank you for raising this issue.Dr Dhttps://www.blogger.com/profile/05774555636055110063noreply@blogger.comtag:blogger.com,1999:blog-5415306683169000572.post-48209854234496433122017-10-06T08:59:38.082-07:002017-10-06T08:59:38.082-07:00Ditto, Alasdair.

My understanding is that aDNA refers to ancient DNA and the use of atDNA is more appropiate for autosomal DNA used for genealogical matching.
